The “circumstances ruling at the time” invite different readings, and a general may easily see “definite military advantage” where civilians (and their lawyers) do not.
Hashing out such questions, as well as sifting evidence, takes time and often the effort of many people — and that costs money that defendants usually don't have. Thus the one issue that has grown to be a recurring difficulty for ICTY defense attorneys is budget, or rather, the fraction of the tribunal's budget that may be spent on a defendant's legal expenses. “This is kind of a bugaboo with us,” says Kostich.
In the ten years since the tribunal was created, the ICTY budget has grown from $276,000 to more than $223 million, which may sound like a lot. But consider this: the Bush administration, in its $87 billion request for the administration of Iraq, requested $100 million just for the investigation of crimes against humanity under Saddam — five hundred investigators at $200,000 apiece. And currently, there's no court to try any criminals those investigators turn up.
At the ICTY, nearly half the budget is earmarked for the office of the prosecutor. The rest must be split among the defense, judges, guards, translators, and many others. Defense attorneys have not only their own expenses and pay to consider, but salaries for aides, investigators, and expert witnesses.
